What’s a “follow-up question”?

I have a challenge for you. Go through your English textbooks and try to find some follow-up questions.

If you’ve ever been frustrated when a simple follow-up question like, “Oh really, what did you buy?” utterly tanks, the answer to why this happens might be in your textbook.

Take the challenge of reviewing your textbook for follow-up questions and I will write another post on this topic this Wednesday (2/8/2012).
